Beleaguered Weather Service defends its forecasts as Texas officials point fingers over flood warnings | CNN Texas forecasters issued a series of early-morning warnings about “life-threatening flooding” along the Guadalupe River.

"One of the NOAA labs slated to be shut down [in Trump's budget] is the National Severe Storms Lab in Norman, Oklahoma, which works to improve flash flood forecasting among other hazards from severe thunderstorms..."

To submit your abstract for the upcoming European Conference on Severe Storms, visit: ecss.eu

Het Deutsches Museum heeft als hoofdthema techniek. Dat zal jou vast wel aanspreken denk ik.

That was an impressive storm of the kind one doesn't see very often.

For a limited number of researchers and forecasters from Europe not able to find sufficient budget to participate, a solution may be available. Please get in touch with me.

Do not forget the Abstract submission deadline of the upcoming European Conference on Severe Storms ⛈️🌪️⚡next Friday 6 June!

We hope to welcome all researchers and forecasters with an interest in severe storms to Utrecht 🇳🇱 this November 🙂!

Happy Europe Day everyone! 🇪🇺

Stand Up for NOAA Research – The Time to Act is Now The AMS is a global community committed to advancing weather, water, and climate science and service.

The 2026 budget passback plan calls for eliminating NOAA Research, the scientific backbone that keeps weather forecasts, alerts, and warnings accurate and effective. This would have disastrous consequences.

Read the AMS statement, in partnership w/ @nwas.org: bit.ly/4cz2RtC

This lab makes it possible for the NWS to forecast severe weather at the level we do. They can do much more too. If lost there’s no going back to fix it.

AEMet has confirmed that the tragic wind event that caused the loss of three people's lives was indeed a tornado:

These plans will be very bad for forecasting and severe weather research in the US. Money invested in NOAA is extremely well spent, let alone the reduction of impacts on people. I am thinking of my US meteorology colleagues and hope this will not become reality. www.cnn.com/2025/04/11/c...

Tres muertos tras el derrumbe por un posible tornado de una nave agrícola en Coria del Río: "Miré y había volado todo" Dos de los muertos, de 61 y 59 años, son hermanos y vecinos de Dos Hermanas, y el tercero, de 40, residía en Benacazón

Sad news that three people were killed as an agricultural warehouse collapsed close to Seville, Spain, due to a tornado or severe wind gusts: www.diariodesevilla.es/sevilla/muer... @clepsidelia.bsky.social

With Fewer Weather Balloons, People in US Heartland Will Be Less Prepared for Tornado Season This could lead to more severe weather-related deaths.

As we’re gearing up for tornado season, taking weather balloons offline in the Heartland of the US, also known as Tornado Alley, will directly affect the NWS’s ability to predict severe weather, including tornado-producing thunderstorms. This could lead to more severe weather-related deaths.

Here is the lightning density map:

A high number of thunderstorms and people working outside. That is about as much as I can say to explain this.

We agree, but reviewer #2 did not. Here is our figure:

A map showing the distribution of fatal lightning accidents across Europe, distinguishing between leisurely and work activities of the impacted people.

A map showing the number of lightning fatalities recorded between 2001 and 2020.

New ESSL study: Lightning kills about 64 people per year across Europe, 78% of them being men. In eastern Europe most victims were at work, whilst in West Europe people engaging in leisure activities are hit more often. Read more in our article here: journals.ametsoc.org/view/journal...

Weet je wie er niet hebben gestemd? Is zulke informatie ergens te vinden?

Er zijn momenten dat de bescherming van democratie en vrijheid echt zwaarder moet wegen dan partijpolitiek (en uitvluchten over geld). Dit was/is zo’n moment.

Alle EU-leiders kozen vorige week voor actieplan om in deze tijd Europa veilig te houden: ReArm Europe.

In hoofdelijke stemming verwerpt de Tweede Kamer zojuist nipt dit plan met steun van PVV, BBB en NSC. Ze gooien daarmee premier Schoof voor de bus en isoleren Nederland.

Oliedom & onverantwoord.

Maar géén schulden. 🥳

Au! Dit is precies de foto die je als Dick Schoof niet wil. In kamp Orban gefrommeld worden. Dan word je nooit meer uitgenodigd voor belangrijke bijeenkomsten in Europa.
